Hi,

it's been a bit but I just wanted to let you know that I got a similar/same
panic (I have a debug kernel on so an assert might have caught it; and I have
local modifications):

/sys/compat/linuxkpi/common/src/linux_80211.c:8723:
linuxkpi_ieee80211_next_txq: Bad link elm 0xfffff800036fa300 prev->next != elm
cpuid = 2
time = 1765156399
KDB: stack backtrace:
db_trace_self_wrapper() at db_trace_self_wrapper+0x2b/frame 0xfffffe0069e87a40
vpanic() at vpanic+0x136/frame 0xfffffe0069e87b70
panic() at panic+0x43/frame 0xfffffe0069e87bd0
linuxkpi_ieee80211_next_txq() at linuxkpi_ieee80211_next_txq+0xe6/frame
0xfffffe0069e87bf0
...

I'll try to work through this during the week.
